Interpreting regression coefficient in simple regression
How is the regression coefficient interpreted in simple regression?
The basic or unstandardized regression coefficient is interpreted as the predicted change in Y (i.e., the DV) given a one-unit change in X (i.e., the IV). It is in the same units as the dependent variable.
- Note that there is another form of the regression coefficient that is important: the standardized regression coefficient. The standardized coefficient varies from –1.00 to +1.00 just like a simple correlation coefficient;
- If the regression coefficient is in standardized units, then in simple regression the regression coefficient is the same thing as the correlation coefficient.
